BEARING FOR CONVEYER-RQLLEBS.'

T0 all whom t may concern.' v

Be-it known that I, JOHAN A. ALVEY, a citizen of the United States, and a resident of the city of St. Louis `and State of Missouri, have invented a new andfuseful Im-A provement in Bearings for Conveyer-Rollers, of which the following is a specification.

My invention relates to bearings for supporting the ends of rollers, and particularly,`

to that type of roller employed with gravity conveyers; although mostv of its advantages may be obtained when it is used in other connections. Y

The principal object of my invention is to provide a bearing for the ends of rollers which will be strong and durable and which may be easily and cheaply manufactured.

A further object is to attain certain other advantages which will be morefully 'set forthhereinafter.

. The invention'consists in the parts, and in Fig 2` is a diametrical section of the cup forming part of the bearing shown in Fig. 1, showing the form of. this 'cup before the parts are assembled; Fig.- 3 is atop plan` view of the spacing member forming part of the bearing shown in Fig. 1, showing it detached from the other parts; Fig.V 4 is a side View of the spacing member shown in Fig.

3; Fig. 5 is a top plan view of the capi forming part of the bearing shown inFig. 1, showin it detached from the other parts; Fig. 6 v1s a side View 'ofthe cap shown in Fig. 5; Fig. 7 is a top plan View of the bearing cup which forms Apart of the bearing shown in Fig. 1, showing it detached from the other parts; Fig. 8 is a side view of the bearing cup shown in Fig. 7; and Fig. 9 is a diametrical section of la modified form of construction embodying my invention, showing it applied to a wooden roller.

For the purpose of illustration, the preferred form of construction embodying the invention, as illustrated in Figs. 1 to 8, is shown in connection with a tubular roller 1, supported at each end by an angle iron 2;

but the inventionis not limited to this exact p construction.

atedV parts for one end of the roller are The bearing and its associshown, auditl is to be` understood that the construction lllustrated is duplicated for the other end of the roller.

Mounted within the end of the roller y1 is a cupy 3. The cup 3 is preferably of soft steel, and in its shape before itis mounted in the roller 1, it is slightly tapered Outward fromthe bottom to the edge', so that whenit is forced into the end of the roller it will t tightly therein. The cup 3, in its shape before the parts of the bearing are assembled, has a narrow. enlargement on its edge forming a shoulderfl'on its inside circumferential In the cup 3 is a spaccated between the bottom and the edge of the cup 3.- The spacing member 5 has integral therewith a pair of legs 7 which are arranged at diametrically opposite points at theouter edge of the spacing member and whichrest upon the bottom of the cup 3.

spread apart slightly at their ends so that when the spacing member is positioned in the .cup 3 the legs 7 will fit tightly against the walls of said cup. Integral with the spacin range member 5 are lugs 8 which are arat diametrically opposite points on the edge of .said spacing member at right angles to said legs 7, and which extend in the opposite direction to said legs.

Within the circumferential edge of the cup 3 is a cap 9 which rests upon the lugs 8 and lthe shoulder 4:, and which is formed with a concave portion l0 in its center. The edgeI of the cup 3 is bent to form a crimp overlying lthe circumferential edge of the cap 9. Withinthe concave portion 10 of the cap 9 is a circular bearing cup`11 having an annularilange 12'engaging the outer face of the cap 9. 'The bearing cup 11 is of hardened steel ,and is pressed tightly into the con: cave portion 110.

The roller 1 is supported by a bearing spindle 13 mounted in the angle iron 2. One end of the bearing spindle 13 is tapered to a point 14 which engages the bottom of the bearing cup 11. The end of the bearing vThe spacing member `5 is preferably of ...spring steel, and in its shape before the parts of the bearing are assembled, the legs spindle 13, adjacent to the point 14;, is formed with a circumferential groove or 'raceway 15 inwhich are bearing rollers 16 engaging the walls of the bearing cup 11.r The major part of the bearing spindle 13 `is screw-threaded and passes loosely through a hole in the angle iron 2. Upon the `bearling spindle 13 are nuts 17 and 18. One nut 17 engages the face of the angle'iron 2 which faces the roller 1, and the othernut 18 enf gages the other face of said angle iron. The nut 17 is formed with a shallow circular recess 19 in one face, Which is arranged to re- ',ceve the ends of the bearing rollers 16 when the nut is adjacent to said bearing rollers. In the modiication shown in Fig. 9," the l cap 20 corresponding to the cap 9 is fastened to the end face of a wooden roller 21by vscrews 22. A bearing cup 23 is secured a concave portionin the cap 20 and isl mounted upon a bearing spindle in the same manner as in the preferred Vform of construction. l

The bearing spindle 13 maybe r.1. djusted `inf the angle iron f2 by manipulating the nuts 17 and 18. -When the `nuts 17 and 18 are 1' ammed tightly Yagainst the faces of the4 yangle iron 2, thev bearingspindle 13 is held fixed in position.` The bearing cup 11, which is thepa-rt subJected to Wear, may

be cheaply made of hardened steel and can be easily replaced when it is Worn. The spacing member 5 holds the cap `9 in posi- Ation when theyedge' of the cup 3 is crimpedv over it, and also supports the Wallsof the concave portion lO'of `the cap 9. The bearing rollersl are loose in the groove 15 in` the bearing'spindle 13, but the nut 17 may be screwed up to position the recess 19 over the ends of these bearing rollers and hold to this exact construction. i

That I claim is: 1. In a bearing for conveyer rollers, a tubular roller, a 'cupfastened in each end of said roller, a cap secured to the edge ofsaid f cup, a smaller bearing cup secured vto saidcap, a spindlel adjustably supported at each end of said roller, and antifriction members between ,the Walls of each.

yand, adapted to receive one end of a spindle.
